2、重载”+”、”-”运算，日期时间加上天数和时间等于新的日期时间，日期时间
减去天数和时间等于新的日期时间；（考虑闰年的情况）
/
用c++的话还是弄成类比较好的，下面是我的解决方法：
#include <ctime>
#include <cstring>
class Timer
{
private:
static const int size = 50;
std::time_t time;
std::tm localTime;
char Ascll[size];
char flag;
public:
Timer()
{
std::time(&time);
flag = 0;
}
~Timer() {}
const char printTime()
{
if(!flag)
{
localTime = std::localtime(&time);
std::strcpy(Ascll, std::asctime(&localTime));
}
flag++;
return Ascll;
}
double timeDiff(Timer time2) const
{
return difftime(time, time2 -> time);
}
} ;
int main()
{
Timer t1;
for(int i = 0; i < 10000; i++ )
{
cout << i;
}
Timer t2;
std::cout << t1printTime() << std::endl;
std::cout << t2printTime() << std::endl;
std::cout << t2timeDiff(&t1) << std::endl;
return 0;
}
以下程序直接显示系统时间
